Electrical connector for electronic module

The invention relates to electrical connectors for electronic modules.

This trend for smaller and higher performance (e.g., faster) electrical systems continues to be competitive and market demand, resulting in higher density electrical systems that have led to the development of surface mount technology. The surface mount technology allows the electronic module to be electrically connected to the contact pads on the surface of the electrical component (eg, a printed circuit, sometimes referred to as a "board" or "printed circuit board"). The electronic module is connected to the electrical component either directly or through an intermediate electrical connector, rather than using a pilot hole extending into the electrical component. Surface mount technology provides a higher component density on the electrical component, which allows for the development of smaller, higher performance systems.

Examples of electrical connectors for such smaller and higher performance electrical systems include a Land-grid array (LGA) socket and a Ball-grid array (BGA) socket. The LGA socket includes an array of electrical contacts electrically coupled to the electrical component and engaging an array of contact pads on the electronic module. The BGA socket also includes an array of electrical contacts that are electrically connected to the electrical component, rather than the contact pads, the aforementioned electrical contacts of the BGA socket engaging the array of solder balls on the electronic module. The aforementioned electrical contacts of both the LGA socket and the BGA socket engage the contact pads on the electrical component or are electrically connected to the electrical component via a solder ball array.

The aforementioned electrical contacts for electrically connecting an electronic module to an electrical component typically include both ground and signal contacts. The ground contacts are located in the array such that the individual signal contacts or signal contacts are differentially surrounded by the ground contacts. The ground contact is thereby used to shield individual or signal contact pairs from adjacent signal contacts or signal contacts. However, in order to provide proper shielding between adjacent signal contacts or signal contact pairs, each signal contact or signal contact pair is generally surrounded by a plurality of ground contacts such that a ground contact can extend over the signal connection. A point or signal contact pair and between adjacent signal contacts or signal contact pairs. The ground contacts occupy the space occupied by the original signal contacts in the array. In other words, the number of ground contacts can limit the overall number of signal contacts that are placed in a connector of a given size and/or within an array having a predetermined number of electrical contacts. In addition, the number of ground contacts can limit the overall density of signal contacts disposed in a connector having a predetermined size and/or in an array having a predetermined number of electrical contacts. Therefore, the use of a plurality of ground contacts to surround individual signal contacts or signal contact pairs limits the development of smaller, higher performance electrical connectors. In addition, the plurality of ground contacts surround the individual signal contacts or signal contacts to limit the relative arrangement of the signal contacts, ground contacts and/or signal contacts in the array, which limits the designer's offer. The ability of the electrical connector to select the configuration of the performance.

There is a need for an electrical connector for an electronic module that accommodates high electrical contact density and provides effective shielding between electrical contacts.

According to the present invention, an electrical connector for electrically connecting an electronic module and an electrical component includes an insulating member having a module side and an opposite component side, the insulating member being configured to extend to the electronic Between the module and the electrical component, the module side faces the electronic module, and the component side faces the electrical component, an electrical contact is held by the insulating component, and the electrical contact includes along the electrical contact The module side of the insulating member is arranged as an array of matching segments, and the matching segments are configured to match a matching contact of the electronic module.

Referring now to Figures 12 and 13, the interconnecting member 720 includes an insulator 728, an array of electrical contacts 722 held by the insulator 728, and a shield 729 secured to the insulator 728. The insulator 728 includes a module side 730 and an opposing component side 732. When the interconnecting member 720 electrically connects the electronic module 16 (first image) to the printed circuit 14 (first image), the insulating member 728 extends between the electronic module 16 and the printed circuit 14 such that the module side 730 The electronic module 16 is facing, and the component side 732 is facing the printed circuit 14. The module side 730 and the component side 732 of the insulator 728 are generally planar as desired. Each electrical contact 722 is referred to herein as a "first" and/or a "second" electrical contact.

Referring now to the thirteenth aspect, electrical contact 722 includes a fixed base 736 that is mechanically coupled to insulator 728 on module side 730. Each electrical contact 722 includes a mating section 766 that extends outwardly from the fixed base 736. The matching section 766 includes a matching interface 768 configured to engage a corresponding contact pad (not shown) on the mating side 24 (first image) of the electronic module 16 (first image) to electrically connect the electrical contact 722 Connected to the electronic module 16. The matching section 766 is a resiliently deflectable spring that is configured to deflect toward the insulator 728 when engaged with the contact pads of the electronic module 16 as desired. In addition to the springs that are resiliently deflectable, a row of elastomers (not shown) is disposed between the fixed base 736 of one or more electrical contacts 722 and the mating segments 766 as desired. The mating section 766 shown herein includes a curved shape that is rewinded onto the fixed base 736. However, the matching section 766 can additionally include any other shape.

Electrical contact 722 includes signal contact 722a and ground contact 722b. The matching interface 768 of the signal contact 722a is a signal pad (not shown) that engages the contact pads on the mating side 24 of the electronic module 16. The mating interface 768 of the ground contact 722b is a ground pad (not shown) that engages the contact pads on the mating side 24 of the electronic module 16. In the exemplary embodiment, the illustrated electrical contact 722 includes four signal contacts 722a and four ground contacts 722b. However, electrical contacts 722 can also include any number of signal contacts 722a and any number of ground contacts 722b. In addition, electrical contacts 722 include any number of signal contacts 722a relative to the number of ground contacts 722b. In some embodiments, electrical contacts 722 include fewer ground contacts 722b than signal contacts 722a.

In the exemplary embodiment, electrical contacts 722 are arranged in two columns 723a and 723b, each of which includes two signal contacts 722a and two ground contacts 722b. In addition, the signal contacts 722a in the aforementioned column 723a are aligned with the signal contacts 722a in the aforementioned column 723b; and the ground contacts 722b in the aforementioned column 723a are aligned with the ground contacts 722b in the aforementioned column 723b. . However, any electrical contact 722 can be selected as the signal contact 722a, and any electrical contact 722 can be selected as the ground contact 722b. In addition, the array of electrical contacts 722 can have any other pattern, relative arrangement, etc. of signal contacts 722a and ground contacts 722b. It should be understood that only a portion of the array of electrical contacts 722 is shown herein; in other words, only a portion of electrical contacts 722 of interconnecting member 720 are depicted herein. The array of electrical contacts 722 can include other electrical contacts 722, not shown, and the array of electrical contacts 722 can include other columns and/or rows.

The fixed bases 736 of at least some of the adjacent electrical contacts 722 are initially mechanically and electrically coupled together via a tab 726. As shown in the thirteenth diagram, the tab 726 has been broken and removed, for example using a stamped opening 740 such that the fixed base 736 of the electrical contact 722 is no longer mechanically and electrically connected together. Thus, the electrical contacts 722 within the array are electrically isolated from each other. The tab 726 has been broken so that the remaining section 726a of the at least one tab 726 extending from each of the ground contacts 722b remains or remains after the tab 726 has been broken. As will be explained below, the remaining section 726a engages the shield 729 to electrically connect the ground contact 722b to the shield 729.

The retention of the remaining section 726a after the tab 726 has been broken is related to the size of the corresponding stamped opening 740. For example, as shown in FIG. 13, the tab 726 can be broken while leaving the stamped opening 740 of the remaining section 726a more than the stamped opening 740 that breaks the tab 726 but leaves the remaining section 726a. small. In this context, each segment 726a is referred to as a "remaining portion" and/or a "shortened tab."

The shield 729 includes a body 731 that is at least partially electrically conductive. The body 731 includes an insulator side 733 and a side 735 opposite the insulating side 733. The body 731 is configured to be secured to the insulator 728 such that the body 731 can cover at least a portion of the module side 730 of the insulator 728. As is apparent from the twelfth figure, when the body 731 of the shield portion 729 is fixed to the insulating member 728, the insulator side 733 of the body 731 faces the module side 730 of the insulating member 728. As desired, when the body 731 is secured to the insulator 728, the insulator side 733 of the body 731 engages the module side 730 of the insulator 728.

Fig. 14 is a perspective view of a portion of the interconnecting member 720, which illustrates the body 731 of the shield portion 729 in a direction opposite to that shown in the twelfth and thirteenth drawings. The fourteenth figure also illustrates the arrangement of the electrical contacts 722 with respect to the shield body 731 when the body 731 is fixed to the insulating member 728 (twelfth and thirteenth views), which will be described below. The body 731 can include any shape that allows the body 731 to shield the electrical contacts 722. In the exemplary embodiment, body 731 of shield 729 is a sheet of material that extends over at least a portion of module side 730 (twelfth and thirteenth views) of insulator 728. In the exemplary embodiment, the body 731 has a block shape as a whole. For example, the body 731 has an overall shape of a parallelepiped. However, the body 731 of the shield 729 may also additionally comprise any other integral shape such as, but not limited to, a cylindrical shape, an elliptical shape, any non-parallel hexahedral shape, and the like. The insulator side 733 and/or the aforementioned side 735 are generally planar as desired. In the exemplary embodiment, the insulator side 733 and the aforementioned side 735 are each a planar side that extends generally parallel to each other. The shield body 731 can have any size including any thickness defined between the insulator side 733 and the aforementioned side 735. In some embodiments, the thickness and/or other dimensions of the body 731 of the shield 729 are selected to provide a predetermined amount of conductivity and/or a predetermined amount of shielding for the body 731.

An anodized layer 737 extends over at least a portion of the shield body 731 as desired. The anodized layer 737 extends over the body 731 of any side, portion, number, section, or the like. In an exemplary embodiment, the anodized layer 737 extends over the entirety of the aforementioned side 735 and the entirety of each side 739, 741, 743, 745 that extends between and interconnects the insulator side 733 and the aforementioned side 735. Above. In the exemplary embodiment, the anodized layer 737 also extends over a portion of the insulator side 733 of the body 731. Section 747 of body 731 is exposed through holes 755 in anodized layer 737 as desired. As will be explained below, the remaining section 726a of the ground contact 722b engages the body 731 of the shield 729 via the aperture 755 to electrically connect the ground contact 722b to the shield body 731.

In the exemplary embodiment, body 731 of shield 729 includes a plurality of openings 749 that extend through aforementioned sides 733 and 735 and pass completely through body 731 therebetween. As will be further explained below, when the shield body 731 is secured to the insulator 728, one or more electrical contacts 722 are received in each of the openings 749. Each opening 749 is defined by at least one inner wall 751 of the body 731. For example, in the exemplary embodiment, each opening is defined by four inner walls 751 that are interconnected at rounded corners as needed. In the exemplary embodiment, the aforementioned four inner walls 751 define an opening 749 having a parallelepiped shape. However, each opening 749 can additionally include any other shape to accommodate electrical contacts 722 that include any shape. Moreover, each opening can be defined by any number of inner walls 751.

Referring again to the twelfth figure, when the shield body 731 is fixed to the insulating member 728, the opening 749 houses the electrical contact 722. In particular, in the exemplary embodiment, the mating segments 766 of each electrical contact 722 are received within a corresponding one of the aforementioned openings 749 such that the inner wall 751 of the opening 749 extends around the mating segment 766. The body 731 of the shield 729 includes a section 753 that extends between adjacent electrical contacts 722 within the array. In an exemplary embodiment, one of the aforementioned electrical contacts 722 is received in each of the openings 749. However, any number of electrical contacts 722 can be accommodated in each of the openings 749. For example, in some alternative embodiments, one or more of the openings 749 accommodate a differential signal pair of the electrical contacts 722. In other alternative embodiments, one or more openings 749 accommodate a set of (two or more) electrical contacts 722. Although eight are shown, the shield 729 can include any number of openings 749 for any number of electrical contacts 722.

When the shield portion 729 is fixed to the insulating member 728 shown in FIG. 12, the body 731 of the shield portion 729 is coupled to the ground contact 722b such that the shield body 731 is electrically connected to the ground contact 722b. More specifically, and referring again to FIG. 14, when the electrical contact 722 is received within the opening 749 of the shield 729, the remaining section 726a of the ground contact 722b is insulated from the fixed base 736 along the body 731. The piece side 733 extends outward. Each of the remaining sections 726a engages the insulator side 733 of the shield body 731 to electrically connect the corresponding ground contact 722b to the shield body 731. In particular, in the exemplary embodiment, the remaining section 726a of the ground contact 722b engages the remaining section 726a of the insulator side 733 of the shield body 731 via the aperture 755 in the anodized layer 737 to ground Contact 722b is electrically coupled to shield body 731.

Referring again to the twelfth figure, when the body 731 of the shield portion 729 is electrically connected to the ground contact 722b, the shield portion body 731 shields the electrical contacts 722 from each other. For example, the inner wall 751 defining the opening 749 of the shield body 731 forms a shield wall that extends between the corresponding electrical contacts 722 and adjacent electrical contacts 722 within the array. As seen in Fig. 12, section 753 forms a shielded section extending between adjacent electrical contacts 722 in the array. The aforementioned wall 751 and section 753 thereby shield adjacent electrical contacts 722 from each other. In an alternative embodiment in which one or more of the openings 749 accommodate a differential pair of electrical contacts 722, the aforementioned wall 751 and section 753 are such that the differential contacts of the electrical contacts 722 are adjacent to each other. The individual contacts 722 are shielded from each other, the adjacent differentials with the contacts 722 are shielded from one another, and/or are adjacent to each other with adjacent sets of more than two contacts 722. Similarly, in an alternative embodiment in which one or more openings 749 accommodate a set (two or more) of electrical contacts 722, the aforementioned wall 751 and section 753 are such that the set of electrical contacts 722 are Adjacent individual contacts 722 are shielded from each other, adjacent differentials with contacts 722 are shielded from each other, and/or adjacent sets containing more than two contacts 722 are shielded from each other.

The fifteenth diagram illustrates an interconnecting member 820 including a shield portion 829 having an opening 749 with the shield portion 729 (twelfth to fourteenth views) (twelfth and fourteenth Figure) Opening 849 of different shapes. The interconnecting member 820 includes an insulator 828, an array of electrical contacts 822 held by the insulator 828, and a shield 829 that is secured to the insulator 828. Each electrical contact 822 includes a mating segment 866 that is configured to engage a corresponding contact pad on the mating side 24 (first image) of the electronic module 16 (first image) to electrically connect the electrical contact 822 to Electronic module 16. In this context, the electrical contacts 822 are each referred to as a "first" and/or a "second" electrical contact.

Shield 829 includes an at least partially electrically conductive body 831. The body 831 of the shield 829 includes a plurality of openings 849 that extend through the body 831. When the shield body 831 is fixed to the insulating member 828, one or more electrical contacts 822 are received in each of the openings 849. In the exemplary embodiment, each opening 849 is defined by a single inner wall 851 of the body 831. The inner wall 851 is shaped such that the aforementioned wall 851 defines an opening 849 having an elliptical shape.
